So here's a shot of one toy adapted with a large switch so you can grasp the concept.
Besides that I bet you are wondering how D is doing without the pacifier.... Yes we are still pacifier free and no going back. Overall he's doing well except he wakes in the middle of the night and has a hard time going back to sleep and then wakes early in the morning everyday. So he is lacking the soothe himself back to sleep part. It's not too fun but I think he will adjust soon, at least I hope.
